NiAFilNE-ENGlNE GOVERNOR.

SPECIFICATION forming part of Letters Application filed December 17,1883.

To wll whom it may concern.-

Be it known that we, ALEXANDER HAMIL- TON BELL and AsrINwALp FULLER, ofthe city, county, and State 05} cw York, have invented a new and usefulImprovement in Automatic Marine-EngineGovernors, of which the followingis a full, clear, and exact description. I

Reference is to be had to the accompanying drawings, forming partofjthis specification, in which similar letters of reference in dicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of our improvement. Fig. 2 is anelevation of one part of the same, showing the valve in place. Fig. 3 isan elevation of the other part, showing a part of the valve-seat.

The object of this invention is to provide governors for marine enginesconstructed in such a manner as to shut off steam automatically. whenthe vessel rolls and pitches.

The invention consists in a marine-engine governor constructed with ashell, a two-part spherical valve-seat placed in the shell, and providedwith flanges to keep it in place, and with perforations for the passageof steam and the valve-stem, asplie'rical valve provided withperforations for the passage of steam and a weighted valve-stem tocontrol the valve, and a stuffing-box and flexible connecting-base toprevent steam from escaping around the valvestem. The valve is held fromturning upon the axis of its stem by a pin attached to the said valve,and which enters a vertical groove in the valve-seat, as will behereinafter fully described.

A B represent the two parts of the shell or case of the governor, whichhave flanges O at their outer ends for COl1VClllQlECO,Ilconnecting thesaid ends with the adjacent flanged ends D of a steam-pipe. The adjacentends of the parts of the shell A B are flared into spherical or globularform, and are provided with flanges E, for convenience in securing thesaid ends to each other. i

In the lower side of the shell A B is formed an opening provided with afixed collar, I having a flange, G, at its outer end.

Within the shell A B are placed semi-spherical plates H I, which haveflanges J around their edges to fit into the rabbeted edges of PatentNo. 297,343, dated April 22, 188

(No model.)

the parts of the said shell A B, and an opening in their lower sidecorresponding with the opening in the said shell A 13. The outsidediameter of the sphere H I is less than the inside diameter of the shellA B to form a space to receive steam. In the center of the part H isformed a large opening, K, and in the other part, I, are formed a numberof small openings, L, which may be circular, oval, square,

formed, or to it is rigidly attached, a stem, 1?,

which passes out through the openings R Q in the sphere H I and shell AB, and has a weight, S, attached to its lowerend, of sufficient gravityto hold the stem I in a vertical position and the sphere M stationary,and causing the sphere H I to turn upon the sphere M as the vessel rocksand pitches. The movement of the sphere H I upon the sphere M partly orwholly closes the openings L O, partly or wholly shutting off steam andslowing or stopping the engine.

Upon the center of the perforated side of the sphere M is formed, or toit is attached, a pin, T, which enters a vertical groove, U, in

the inner surface of the sphere II I, to pre went the said sphere M fromrotating upon the axis of the stem P, and thus getting out of place andpreventing the perforations L 0 from registering properly. The lowerpart of lthe stem 1 passes throu to which is attached the outer end of ashort flexible hose, W. The other end of the hose W is secured to theflanged collar F G either directly or by means of a flanged collar, X Y,interposed between the said collar F hose 7. With this construction theescape of steam will be prevented, and the weighted lower end ofithestem I allowed to have a free lateral movement.

Having thus fully described our we claim as new and desire to secure byLetters Patent- In the other side of the 65 gh a stufling-box, V, 99

G and 5 invention, :00

1. A marine-engine governor constructed substantially as herein shownand described, and consisting of the shell A Bfthe two-part sphericalva1ve-seat II I, having flanges J and perforations K L R, the sphericalvalve M, having perforations N O, and provided with a Weightedvalve-stem, P, and the stu'liing-box V and flexible connecting-h ose WV,as set forth.

2. In a marine-engine governor, the combination, with the shell A B, ofthe twopart spherical valve-seat II I, having flanges J and perforationsK L R, and the spherical valve M, having perforations N O, and weightedstem 1 S, substantially as herein shown and described, whereby theadmission of steam will bereg'nlated and stopped by the rocking andpitching of the vessel, as set forth.

3. In a marine-engine governor, the valve constructed substantially asherein shown and described,and consist-i ngol'thetwopart spherical seatII I, having flanges J and perforations K I) R, and the spherical valveM, having, perforations N O, and weighted stem 1, whereby the rockingand pitching of the vessel will move the said valve to partlyor fullyshut ofi steam, as set forth.

4. In a marine-engine governor, the combination, with the valve-seat HI, having vertical slot U, and the valve M, of the pin '1, substantiallyas herein shown and described, whereby thesaid valve is kept fromturning about the axis of its stern, and taking its perforations out ofregister with the perforations of the valve-seat, as set forth.

5. In a inarineengine governor, the combination, with the collar F ofthe shell A B, and the valve-stein I, of the stuffing-box V, and theflexible hose W, substantially as herein shown and described, wherebythe escape of steam around the oscillating valve-stem will be n'evented,as set forth.
